I Tried Every AI Video Generator - Seedance 2.5 vs Minimax h3 vs Flux 3
A detailed comparison of Seedance 2.5, Seedance 2.0, MiniMax H3, and Flux 3 across video quality, prompt following, cinematic shots, acting, dialogue, audio, music videos, and multi-reference generation. The video also compares generation costs, resolution, duration, references, and the best use cases for each AI video model.
AI Video Generator Comparison
This video compares four AI video generation models: Seedance 2.5, Seedance 2.0, MiniMax H3, and Flux 3. The tests focus on generation quality, prompt adherence, cinematic performance, emotion, dialogue, audio, music videos, and reference-image consistency.
Seedance 2.0
Seedance 2.0 is presented as the older benchmark model in the comparison. It supports generations up to 15 seconds and offers 480p, 720p, 1080p, and 4K output. The video highlights its 4K capability and describes it as a strong option for simple cinematic scenes.
Seedance 2.5
Seedance 2.5 is tested as the newest and most capable model in the comparison. It supports generations up to 30 seconds and can use multiple reference inputs, including image, video, and audio references. The video highlights its strong prompt following, cinematic quality, acting, emotional progression, dialogue, and ability to work with many references.
MiniMax H3
MiniMax H3 supports videos up to 15 seconds at 2K resolution and allows multiple references. The video also discusses its ability to run locally, making it an interesting option for users with powerful hardware.
Flux 3
Flux 3 supports 1080p generations up to 20 seconds and is highlighted for its audio quality, documentary-style videos, realistic textures, dialogue, and cinematic close-ups.
Camera Movement Test
The first major test evaluates camera movements including a crash zoom, whip pan, and Earth zoom-out. Seedance 2.5 performs best overall in following the sequence smoothly. MiniMax and Seedance 2.0 also perform reasonably well, while Flux 3 struggles more with following the exact camera instructions.
Cinematic Shot Test
The cinematic tests use image references to evaluate camera movement, visual quality, physics, acting, and cinematic feel. Seedance 2.0 benefits from its crisp 4K output, while Seedance 2.5 provides strong cinematic results and particularly good audio.
Advanced Cinematic Test
The advanced test combines an image reference, dialogue, multiple camera angles, shadows, character acting, and physical movement. Seedance 2.5 performs strongly across these requirements. MiniMax shows good prompt coherence, while Flux produces sharp character details but struggles more with following the complete prompt.
Text-to-Video Test
A Viking-era text-to-video scenario is used to compare cinematic storytelling, dialogue, multiple shots, realism, and visual consistency. Seedance 2.5 produces a highly realistic result with strong adherence to the requested scene, while Flux produces impressive audio and close-up shots.
Emotion and Acting Test
The models are tested on a character progressing from a neutral expression to happiness, sadness, and eventually crying. Seedance 2.5 performs particularly well at subtle emotional progression and realistic acting. Flux also produces strong results, while MiniMax shows a more artificial appearance around the tears.
Dialogue and Voice Test
The dialogue test evaluates character performance and voice generation. Seedance 2.5 delivers strong acting and emotional performance. Flux produces one of the most realistic voices in the comparison, although its speech can become too fast and difficult to understand.
Music Video Test
The video also tests AI-generated music videos using references and prompts for modern pop music. The results demonstrate that AI music generation can sometimes produce output that resembles existing copyrighted music, so creators should be careful when using generated songs commercially.
Multi-Reference Test
The final major test uses multiple references to create a crime-investigation-style video. Seedance 2.5 handles the references more effectively than the other models tested. Seedance 2.0, MiniMax, and Flux have more difficulty integrating all of the references into the requested narrative.
Overall Results
- Seedance 2.5: Best overall performance, prompt adherence, acting, cinematic generation, and multi-reference handling.
- Seedance 2.0: Strong choice for simple scenes where 1080p or 4K output is important.
- MiniMax H3: Strong prompt coherence and local-generation capabilities.
- Flux 3: Strong dialogue, audio, realistic textures, documentary-style visuals, and cinematic close-ups.
Final Recommendation
The video recommends Seedance 2.5 when users can accept 720p output and want the strongest overall generation quality. Flux 3 is worth considering for dialogue and voice-heavy videos. MiniMax H3 may appeal to users interested in local generation, while Seedance 2.0 remains useful for simple scenes where 1080p or 4K output is required.
Key Takeaways
- Seedance 2.5 is the strongest overall model in the creator's testing.
- Seedance 2.0 remains valuable because of its 1080p and 4K capabilities.
- MiniMax H3 performs well for prompt coherence and local workflows.
- Flux 3 stands out for realistic dialogue and audio.
- Different models perform better for different creative workflows.
